Which is the most efficient way to add cases to a switch script?

"changing player health","change player health","changeplayerhealth","changehealth","change health"

Are the spaces required/needed?
Are added cases similar to command expressions? Is "change health" = "changehealth" = "chan health"?
If 'chan play heal' was typed in, would it get matched above? Would "common scripts" = "common scripts room"?
Would a selection with "if then else room" produce an error if a difference case had "if else room"?

Just trying to save time here before I get too deep!

Thanks!

Switch looks for an exact match, so yes, you need the spaces. However, you could test against true, and use IsRegexMatch:

switch (true) {
  case (IsRegexMatch("chan.*health", s)) {
    msg("here")
  }
  default {
    msg("not here")
  }
}

The "chan.*health" is a regular expression that will match anything like that, where the .* bit matches anything (or nothing).

Oooh. Nice. Thanks!
